Severe stuttering and GPU drops to 0% when moving (PC, DX12) — since June 11th, 2025

Since the update on June 11th, Fortnite has become unplayable for me on PC.

Every time I press a movement key (WASD), the GPU usage drops instantly to 0% and the game freezes or stutters heavily. The moment I stop moving, GPU usage returns to ~30–40%.

This happens only in Fortnite—other games like Far Cry 6 run perfectly on ultra settings.

I’ve tried everything: reinstalling Fortnite and Epic Launcher, clearing NVIDIA DXCache shader folders, latest GPU drivers, switching DirectX modes, disabling overlays, minimal USB setup, safe mode, etc.

Anyone else seeing this exact behavior since June 11th? I’ve seen some chatter on Jodel and forums, so wondering how widespread this is.

Specs: RTX 4070 Ti SUPER, i5-14600KF, 32GB RAM, Windows 11, DX12

🤕 Help appreciated!
